Why do all buses take a minute waiting at the bus stops when it arrives there?

Like it just sits there waiting for some reason. Is that why they’re late at times.

    They usually don't do that.  If they stop for extra time at a stop, it usually means they're a little ahead of schedule.

    The drivers are trying to properly time arrivals and departures to stay on schedule.

    "All buses" means "every bus in the world", are you sure they all do that?

    They don’t all do that. 

    But all bus timetables try to run on time, and if buses encounter traffic which is lighter than usual then they can end up running ahead of schedule.

    When that happens bus drivers are instructed to perform “modulation” to remain on schedule. So if they find that they’re, say, six minutes ahead, then they might wait for ninety seconds at the next four stops or for one minute at the next six stops. Sometimes they receive direct orders by radio or datalink to do that, other times they’ll use their own initiative. 

    If drivers know that they’re a few minutes ahead but a little later in the journey know from experience that they’ll lose that time then they won’t modulate. Ideally if that pattern is a daily predictable event then they feedback that information to the route schedulers who may adjust the timetable to reflect reality.

    The driver isn't allowed to depart before the scheduled time, so if he has time in hand he has to wait until then.

    Usually, because they are a bit ahead of schedule and don't want to be early at the next stops.  Just the opposite of the problem you ask about.
